Remove images by size

[kristallaju]

How to remove images with preg_replace by size lets say if image is smaller than 10X10px then it will be removed

[cags]

preg_replace is a Regular Expression function for replacing one string pattern with another, I don't see what this has to do with checking the size of an image?

[kristallaju]

Any other ways maybe?

Certainly, the getimagesize function should suffice for your requirements.

 

<?php
$size = getimagesize($path);

if($size[0] < 10 || $size[1] < 10) {
  // it's too small
} else {
  // it's fine
}
?>

&& would probably be better to use otherwise something that's like 9X100 would get deleted which isn't what the OP wanted (at least from what I can tell).

Ok basically its great solution but how to put it in my script

 

<?php

function rewriter( $body, $case_sensitive=false ) {

include "inc/synodb.php";
include "inc/config.php";
include "inc/badword.php";



$synlist=$body;
	 $synchar = array("(", ")", "[", "]", "?", ".", ",", "|", "\$", "*", "+", "^", "{", "}");
	 $synlist=str_replace($synchar," ",$synlist);
	 $synlist=str_replace("  "," ",$synlist);
	 $my_synlist = explode(" ",$synlist);
         $body = preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $body);
         $body =  preg_replace('/\b('.implode('|',$badword).')\b/','',$body);


	if (sizeof($my_synlist)>0)
	{

	for($i=0;$i<sizeof($my_synlist);$i++)
		{

		$synorand = rand(1,100);
		if($synorand < $percsyno)

			{

			$syn_replace=$my_synlist[$i];
			$syn_replace=str_replace(" ","",$syn_replace);

			$syn_replace=" ".$syn_replace." ";

			$syn_replace_target=$syndb[$syn_replace];



			if(($syn_replace!="")&&($syn_replace!=" ")&&($syn_replace_target!=""))
				{

				$body = str_replace($syn_replace,$syn_replace_target,$body);

				}

			}
		}
	}

return $body;
}


?>

 

ok i managed to make it remove non acii characters and predefined words but dont get how to get it to work with your script?

[kristallaju]

Still no luck ok maybe some more info would help my script uses simplepie to get content from feed so i need to remove images from cache i just dont get how to do it

[kristallaju]

Figured out that it would be best to remove it still with preg_replace but i wanna to remove ovly images which contain width="1" is it possible?

[kristallaju]

I tried like this

$string= "<img width='1' />";
echo $string = preg_replace("/<img[^>]+>/i","",$string);

 

Works great but removes all images

I think your gonna have to be clearer about what your trying to do. When you mentioned removing images, we assumed you meant removing actual images, but the more you talk the less likely it seems this is what you want to do. It appears now that you wish to parse HTML text, and remove the <img /> tag for any image that has a width or height (or some combination) below a certain value. Is this the case? If it is, to what purpose? Where are you getting the HTML from initially?
